Measurement of inclusive J/ψ pair production cross section in pp collisions at √s=13 TeV
The production cross section of inclusive J/ψ pairs in pp collisions at a center-of-mass energy √s=13 TeV is measured with ALICE. The measurement is performed for J/ψ in the rapidity interval 2.5<y<4.0 and for transverse momentum pT>0. The production cross section of inclusive J/ψ pairs is...

| Zusammenfassung: | The production cross section of inclusive J/ψ pairs in pp collisions at a center-of-mass energy √s=13 TeV is measured with ALICE. The measurement is performed for J/ψ in the rapidity interval 2.5<y<4.0 and for transverse momentum pT>0. The production cross section of inclusive J/ψ pairs is reported to be 10.3±2.3(stat.)±1.3(syst.) nb in this kinematic interval. The contribution from nonprompt J/ψ (i.e., originated from beauty-hadron decays) to the inclusive sample is evaluated. The effective double-parton scattering cross section is computed, neglecting the single-parton scattering contribution. |
